The Sea to Summit Lightweight Compression Sack in a 35-liter size is designed to help you tame bulky clothing and gear, freeing up valuable packing space for outdoor adventures or travel. By compressing contents to roughly one-third of their original volume, this sack can make a meaningful difference when you’re balancing gear, footwear, and essentials in a backpack, suitcase, or duffle.
Crafted from bluesign-approved 70D PU-coated nylon, it pairs durability with a lightweight build. A white interior coating aids visibility and helps items inside you locate quickly, while moisture resistance helps keep contents from getting damp during mixed-weather trips. This combination supports a streamlined packing routine without adding unnecessary weight.
An attached flip-top lid prevents straps from tangling as you compress or access gear. The drawcord closure provides quick, reliable access, so you can grab what you need on the move. A three-strap system—two ladderlock buckles and one side-release buckle—delivers even compression and flexible capacity for different loads.
In the 35-liter configuration, the sack measures 11.3 x 22.8 inches and weighs about 0.37 pounds. It’s designed for flexibility, whether you’re packing a compact day kit for a weekend trip or organizing group gear for longer journeys. Note: the sack is water-resistant, not waterproof, so consider your packing needs and external protection in wet conditions.
